In most of our PBX's, there is a large number of trunk groups that are consistantly at capacity. When I mention this to our 'engineers', they state that it is OK because the calls will over flow to another trunk group via ARS. I can not beleive that this over flow situation would be OK. I thought overflow was a backup to the primary path. There must be some derogatory impact on the switch or the call handling. Please give me your opinions.
